For other noise complaints, here are the cities guidlines:
"Large party nuisance - the creation of plainly audible sound that emanates from a gathering of 10 or more people, where the gathering is not completely contained within a structure and is audible across a property line, through partitions, or at a distance of 100 feet.
This ordinance can be enforced during the day and night."
